The futility of universal pre-employment chest radiographs.

In a developmental center, a preemployment chest x-ray was required for all job applicants. We scrutinized the pros and cons of this practice through a review of the medical literature and our experience, and discussion with our colleagues. We concluded that such chest x-ray caused unwarranted radiation exposure, did not produce compliance with the tuberculosis laws, gave a false sense of security regarding workers' compensation risk management, was contrary to established occupational medicine practice guidelines, and was unnecessary and wasteful. We discontinued such chest x-rays. The purpose of the pre-employment examination should remain narrowly job related. Even long-established procedures require periodic utilization review.
